This is a stand up zip lock spice bag, material: PET/AL/PE, thickness: 120 microns/side, size:18*23+8cm, MOQ: 20,000 pcs.

Some people may have some questions about the material AL and VMPET, the differences between AL and VMPWT are like pure gold and gold plating, AL is pure foil, while VMPET is not. When you need to last your product’s shelf life, Al will be a better choice on waterproof and UV resistant. Then how to distinguish them, you can turn on the flashlight of your phone, then put it into the bag, if you can see the lights out of the bag, then its VMPET, while if there is no lights leak out, then its AL.
